Paddy field dermatitis among inhabitants near the mouth of the Kiso River. (2). Survey on the snail intemediate hosts for avian schistosome cercariae / 日本農村医学会雑誌

ABSTRACT

Surveys on the snail intermediate hosts were undertaken in the paddy fields in Yatomi-cho, Aichi Prefecture, once a year over a 5-year period (1983-1987).<BR>And the cercariae of two different avian schistosomes were detected from snails in paddy fields.<BR>The cercariae from Polyplis haemisphaerula were identified as species beloning to the genus Gigantobilharzia and the cercariae from austropeplea ollula as species belonging to the genus Trichobilharzia.<BR>It was concluded that the paddy field dermatitis occurring in Yatomi-cho was proved to be caused by the invasion of these cercariae.
